Standard/Guidance Document Referenced (if applicable): N/A 5 L. Test Principle: Target Selection The cobas® HSV 1and 2 Test utilizes real-time PCR technology to detect the conserved regions of HSV-1 Thymidine Kinase and HSV-1 DNA Polymerase as well as HSV-2 Thymidine Kinase and HSV-2 Glycoprotein B genes. Fluorogenic target-specific probes are used for the detection of the amplified HSV-1 and HSV-2 DNA as well as Internal Control. Since two HSV type targets are detected with different fluorescent dyes, the cobas® HSV 1 and 2 Test has the ability to simultaneously detect and differentiate HSV-1 and HSV-2. Primer and probe oligonucleotide sequences were designed to select HSV-1 and HSV-2 conserved sequences without cross reacting to other viruses, or other bacterial organisms commonly found in human genital areas. Sample Preparation Sample preparation for the cobas® HSV 1 and 2 Test is automated with the use of the cobas® x 480 instrument. Organisms from swab specimens collected in MSwab medium are lysed with chaotropic agent, proteinase K, and SDS reagents. Released nucleic acids, along with added Internal Control DNA, are bound by magnetic glass particles. The particles are washed and the bound nucleic acids are then eluted into a small volume of buffer. The instrument then takes an aliquot of the eluted material and sets up the PCR reaction with an activated Master Mix. PCR Amplification and TaqMan® Detection The PCR cycling steps and detection of target signal occurs in the cobas® z 480 Analyzer. The Master Mix reagent contains primer pairs and probes for HSV-1, HSV-2 and Internal Control targets. If the target nucleic acid sequences are present, amplification with the corresponding primers will occur by a thermostable DNA polymerase, generating PCR products (amplicons). These products are detected by specific TaqMan probes containing a fluorescent dye and a quencher. Normally, the quencher

H. Intended Use: 1. Intended use(s): The Liofilchem® MTS (MIC Test Strip) Penicillin 0.002-32 μg/mL is a quantitative method intended for the in vitro determination of antimicrobial susceptibility of bacteria. MTS consists of specialized paper impregnated with a pre-defined concentration gradient of an antimicrobial agent, which is used to determine the minimum inhibitory concentration (MIC) in μg/mL of antimicrobial agents against bacteria as tested on agar media using overnight incubation and manual reading procedures. The MTS™ Penicillin at concentrations of 0.002 - 32 μg/mL should be interpreted at 20-
24 hours of incubation for Streptococcus spp. MTS™ Penicillin can be used to determine the MIC of penicillin against the following bacteria. Penicillin has been shown to be active both clinically and in vitro against these bacterial species according to th e FDA drug approved label: Streptococcus pneumoniae Streptococcus pyogenes (Group A) Streptococcus dysgalactiae (Group C & G) Streptococcus anginosus (Group C & G) Streptococcus constellatus (Group C & G) Streptococcus intermedius (Group C & G) 2. Indication(s) for use: Same as Intended Use 3. Special conditions for use statement(s): · For prescription use · The ability of the MTS to detect resistant isolates with the following drug/bacterial species combinations is unknown because resistant isolates were either not available or an insufficient number was encountered at the time of comparative testing.

Device Description: The Penicillin MIC Test Strip (MTS) consists of specialized paper impregnated with a predefined concentration gradient of Penicillin across 15 two-fold dilutions similar to dilutions used by conventional MIC methods. One side of the strip is labelled with the Penicillin code (P) and the MIC reading scale in µg/mL. When the MIC Test Strip is applied onto an inoculated agar surface, the preformed exponential gradient of antimicrobial agent is immediately transferred to the agar matrix. After 20-24 hours incubation, a symmetrical inhibition ellipse centered along the strip is formed. The MIC is read directly from the scale in terms of µg/mL at the point where the edge of the inhibition ellipse intersects the MIC Test Strip. Since MTS strip generates MIC values which fall between two-fold dilutions for interpretation, the MIC value read is recorded to the next two-fold dilution value. J.

L. Test Principle: The Liofilchem MIC Test Strips (MTS) are made of specialized paper impregnated with a predefined concentration gradient of antibiotic, across 15 two-fold dilutions similar to dilutions used by conventional MIC methods. When the MIC Test Strip is applied onto an inoculated agar surface, the preformed exponential gradient of antimicrobial agent is immediately transferred to the agar matrix. After 20-24 hours incubation (time specific to Liofilchem MTS, Penicillin), a symmetrical inhibition ellipse centered along the strip is formed. The MIC is read directly from the scale in terms of µg/mL at the point where the 5
edge of the inhibition ellipse intersects the strip MIC Test Strip. Growth along the entire gradient (i.e., no inhibition ellipse) indicates that the MIC value is greater than or equal to (≥) the highest value on the scale. An inhibition ellipse that intersects below the lower end of the scale is read as less than (<) the lowest value. An MIC of 0.125μg/mL is considered to be the same as 0.12μg/mL for reporting purposes. An MTS MIC value which falls between standard two-fold dilutions must be rounded up to the next standard upper two-fold value before categorization. M. Performance Characteristics: 1. Analytical performance: a. Precision/Reproducibility: Reproducibility testing was conducted at three sites using ten Gram-positive organisms. Each isolate was tested in triplicate over three days. The reproducibility panel included four S. pyogenes, one S. anginosus, one S. constellatus, one S. intermedius, and three S. pneumoniae isolates. The mode MIC values were pre-
determined and the reproducibility was calculated based on the number of MIC values that fell within ±1 doubling dilution of the mode MIC values. All MIC results were on scale. The testing resulted in overall reproducibility of 100%. The results were acceptable. b. Linearity/assay reportable range: Not applicable c. Traceability, Stability, Expected values (controls, calibrators, or methods): Quality Control (QC) Testing: The CLSI recommended QC strain, S. pneumoniae ATCC 49619, was tested a sufficient number of times (i.e., at least 20/site) at each testing site using both MTS and reference methods.

H. Intended Use: 1. Intended use(s): The Liofilchem® MTS (MIC Test Strip) Penicillin 0.002-32 μg/mL is a quantitative method intended for the in vitro determination of antimicrobial susceptibility of bacteria. MTS consists of specialized paper impregnated with a pre-defined concentration gradient of an antimicrobial agent, which is used to determine the minimum inhibitory concentration (MIC) in μg/mL of antimicrobial agents against bacteria as tested on agar media using overnight incubation and manual reading procedures. The MTS™ Penicillin at concentrations of 0.002 - 32 μg/mL should be interpreted at 20-
24 hours of incubation for Streptococcus spp. MTS™ Penicillin can be used to determine the MIC of penicillin against the following bacteria. Penicillin has been shown to be active both clinically and in vitro against these bacterial species according to th e FDA drug approved label: Streptococcus pneumoniae Streptococcus pyogenes (Group A) Streptococcus dysgalactiae (Group C & G) Streptococcus anginosus (Group C & G) Streptococcus constellatus (Group C & G) Streptococcus intermedius (Group C & G) 2. Indication(s) for use: Same as Intended Use 3. Special conditions for use statement(s): · For prescription use · The ability of the MTS to detect resistant isolates with the following drug/bacterial species combinations is unknown because resistant isolates were either not available or an insufficient number was encountered at the time of comparative testing.

Device Description: The Penicillin MIC Test Strip (MTS) consists of specialized paper impregnated with a predefined concentration gradient of Penicillin across 15 two-fold dilutions similar to dilutions used by conventional MIC methods. One side of the strip is labelled with the Penicillin code (P) and the MIC reading scale in µg/mL. When the MIC Test Strip is applied onto an inoculated agar surface, the preformed exponential gradient of antimicrobial agent is immediately transferred to the agar matrix. After 20-24 hours incubation, a symmetrical inhibition ellipse centered along the strip is formed. The MIC is read directly from the scale in terms of µg/mL at the point where the edge of the inhibition ellipse intersects the MIC Test Strip. Since MTS strip generates MIC values which fall between two-fold dilutions for interpretation, the MIC value read is recorded to the next two-fold dilution value. J.

H. Intended Use: 1. Intended use(s): The Liofilchem® MTS (MIC Test Strip) Penicillin 0.002-32 μg/mL is a quantitative method intended for the in vitro determination of antimicrobial susceptibility of bacteria. MTS consists of specialized paper impregnated with a pre-defined concentration gradient of an antimicrobial agent, which is used to determine the minimum inhibitory concentration (MIC) in μg/mL of antimicrobial agents against bacteria as tested on agar media using overnight incubation and manual reading procedures. The MTS™ Penicillin at concentrations of 0.002 - 32 μg/mL should be interpreted at 20-
24 hours of incubation for Streptococcus spp. MTS™ Penicillin can be used to determine the MIC of penicillin against the following bacteria. Penicillin has been shown to be active both clinically and in vitro against these bacterial species according to th e FDA drug approved label: Streptococcus pneumoniae Streptococcus pyogenes (Group A) Streptococcus dysgalactiae (Group C & G) Streptococcus anginosus (Group C & G) Streptococcus constellatus (Group C & G) Streptococcus intermedius (Group C & G) 2.

Device Description: The Penicillin MIC Test Strip (MTS) consists of specialized paper impregnated with a predefined concentration gradient of Penicillin across 15 two-fold dilutions similar to dilutions used by conventional MIC methods. One side of the strip is labelled with the Penicillin code (P) and the MIC reading scale in µg/mL. When the MIC Test Strip is applied onto an inoculated agar surface, the preformed exponential gradient of antimicrobial agent is immediately transferred to the agar matrix. After 20-24 hours incubation, a symmetrical inhibition ellipse centered along the strip is formed. The MIC is read directly from the scale in terms of µg/mL at the point where the edge of the inhibition ellipse intersects the MIC Test Strip. Since MTS strip generates MIC values which fall between two-fold dilutions for interpretation, the MIC value read is recorded to the next two-fold dilution value. J.

L. Test Principle: The Liofilchem MIC Test Strips (MTS) are made of specialized paper impregnated with a predefined concentration gradient of antibiotic, across 15 two-fold dilutions similar to dilutions used by conventional MIC methods. When the MIC Test Strip is applied onto an inoculated agar surface, the preformed exponential gradient of antimicrobial agent is immediately transferred to the agar matrix. After 20-24 hours incubation (time specific to Liofilchem MTS, Penicillin), a symmetrical inhibition ellipse centered along the strip is formed. The MIC is read directly from the scale in terms of µg/mL at the point where the 5
edge of the inhibition ellipse intersects the strip MIC Test Strip. Growth along the entire gradient (i.e., no inhibition ellipse) indicates that the MIC value is greater than or equal to (≥) the highest value on the scale. An inhibition ellipse that intersects below the lower end of the scale is read as less than (<) the lowest value. An MIC of 0.125μg/mL is considered to be the same as 0.12μg/mL for reporting purposes. An MTS MIC value which falls between standard two-fold dilutions must be rounded up to the next standard upper two-fold value before categorization. M. Performance Characteristics: 1. Analytical performance: a. Precision/Reproducibility: Reproducibility testing was conducted at three sites using ten Gram-positive organisms. Each isolate was tested in triplicate over three days. The reproducibility panel included four S. pyogenes, one S. anginosus, one S. constellatus, one S. intermedius, and three S. pneumoniae isolates. The mode MIC values were pre-
determined and the reproducibility was calculated based on the number of MIC values that fell within ±1 doubling dilution of the mode MIC values. All MIC results were on scale.

Method comparison with predicate device: The MTS, Penicillin was evaluated at three sites located within the United States. Each clinical isolate was tested one time by MTS, Penicillin and the reference method using the same initial standardized suspension. A total of 239 clinical fastidious Gram-positive isolates were tested which included 100 β-hemolytic Streptococcus spp. (60 S. pyogenes and 40 S. dysgalactiae), 48 Viridans Streptococcus spp. (23 S. 7
anginosus, 4 S. intermedius, and 21 S. constellatus), and 91 S. pneumoniae isolates. Of the clinical isolates, 54% were contemporary isolates tested within 6 months of isolation. All clinical isolates grew on the Mueller Hinton with 5% blood plate with the Penicillin MTS strip. Challenge testing was performed at one internal site. A total of 50 challenge fastidious Gram-positive isolates were tested which included 10 S. pyogenes, 15 Viridans Streptococcus spp. (7 S. anginosus, 2 S. constellatus, 6 S. intermedius), and 25 S. pneumoniae isolates. Results obtained with the Liofilchem MIC Test Strip (MTS), Penicillin were compared to results obtained with the CLSI broth microdilution reference panel. The same clinical and challenge isolates for S. pneumoniae were evaluated using both sets of interpretive criteria for meningitis and non-meningitis. The reference panel contained two-fold serial dilutions of penicillin with a range of 0.002 – 32 μg/mL. The testing conditions for the reference method were consistent with CLSI guidelines as listed in the CLSI document M07-A10. Isolated colonies from an overnight blood agar plate were suspended in saline to achieve a 0.5 McFarland standard turbidity (approximately 108 CFU/mL). Testing conditions consisted of incubation of the inoculated Mueller Hinton agar plates with 5% sheep blood in an inverted position at 35°C ± 2° for 20-24 hours. At the end of incubation, the MIC value at which the edge of the inhibition ellipse intersected the strip was compared to MIC results obtained with the reference method. The performance for the total 289 clinical and challenge isolates is summarized in Table 3 below. 8

83-Microbiology H. Intended Use: 1. Intended use(s): The TECHLAB H. PYLORI QUIK CHEK test is a rapid membrane enzyme immunoassay for the qualitative detection of Helicobacter pylori specific antigen in a single use cassette. It is intended for use with human fecal specimens to aid in the diagnosis of H. pylori infection and to demonstrate loss of H. pylori antigen following treatment. The test can be used with unpreserved fecal specimens and fecal specimens preserved in transport media from patients suspected of H. pylori infection. Testing of patients to demonstrate loss of H. pylori antigen following treatment should be performed no sooner than 4 weeks after completion of the treatment regimen. Test results should be taken into consideration by the physician in conjunction with the patient history and symptoms. 2. Indication(s) for use: Same as the Intended Use. 3. Special conditions for use statement(s): For prescription use only 4. Special instrument requirements: None I. Device Description: The H. PYLORI QUIK CHEK test utilizes antibodies specific for H. pylori antigen in human fecal samples. The Membrane Device contains a “Reaction Window” with two vertical lines of immobilized antibodies. The test line (“T”) contains antibodies specific for H. pylori antigen. The control line (“C”) contains antibodies to horseradish peroxidase (HRP). The “Conjugate” consists of antibodies to H. pylori antigen coupled to horseradish peroxidase. After incubation, the Reaction Window is examined visually for the appearance of vertical blue lines on the “C” and “T” sides of the Reaction Window. A blue line on the “T” side of the Reaction Window indicates a positive result. A positive “C” reaction, indicated by a vertical blue line on the “C” side of the Reaction Window, confirms that the sample and reagents were added correctly, the reagents were active at the time of performing the assay, and that the sample migrated properly through the Membrane Device. It also confirms the reactivity of the other reagents associated with the assay. 3

M. Performance Characteristics (if/when applicable): 1. Analytical performance: a. Precision/Reproducibility: The reproducibility of the H. PYLORI QUIK CHEK test was determined using an eight member masked fecal specimen panel. The panel consisted of 2 negative, 2 high negative (just below C5), 2 low positive (just above LoD), and 2 moderate positive (3-4x higher than the C95) specimens. Each fecal specimen was spiked using a known concentration of H. pylori purified flagellar antigen from whole organism to achieve the desired concentration. Testing was performed at 2 independent laboratories and on-site at TECHLAB, Inc. The Specimens were tested twice a day in triplicate over a five day period by multiple technicians at each site using two different kit lots. Positive and negative controls were run with each sample panel of masked specimens. The result from each laboratory were submitted to TECHLAB Inc. and compared. The results for the positive control, negative control, true negative, low positive, and moderate positive, was consistent among all three locations with100% reproducibility for all test panels. The high negative provided a positive result 63 out of 180 observations. b. Linearity/assay reportable range: Not applicable. c. Traceability, Stability, Expected values (controls, calibrators, or methods): Sample stability study: The effect of specimen storage on antigen stability was evaluated for both fresh stool samples and stool samples in transport media. The following transport media were used for the study: Thermo Scientific Protocol Cary Blair media and Thermo Scientific Protocol C&S media. For the analysis, a total of 32 fecal specimens were tested with the H. PYLORI QUIK CHEK test. The samples were prepared using a negative fecal matrix and spiked with H. pylori antigen (ATCC strain 43526). The panel consisted of 2 negative, 5 high negative (C5), 10 low positive (1-2x C95), and 15 positive specimens covering the range of the test (For fresh and preserved specimens this range was 50 ng/mL – 1200 ng/mL). Fresh samples were stored at refrigerated temperatures (between 2ºC and 8ºC) and room temperatures (between 20ºC and 25ºC) and were tested at 0, 24, 48,72 and 96 hours. Positive and negative controls were also tested at each timepoint. Fecal specimens added to Cary Blair and C&S media were transported as recommended in their respective package inserts; samples were stored at refrigerated temperatures (between 2ºC and 8ºC) and room temperatures (between 20ºC and 25ºC) and were tested at 24 hour intervals from 0 to 96 hours. 6
For fresh samples stored at refrigerated and room temperatures, the positive and negative samples gave the expected results 100% of the time. Storage in Cary Blair and C&S transport media did not affect the stability of the samples. Based on these results, the recommended storage time for fresh, Cary Blair, and C&S stored samples is up to 96 hours

The following transport media were used for the study: Thermo Scientific Protocol Cary Blair media and Thermo Scientific Protocol C&S media. For the analysis, a total of 32 fecal specimens were tested with the H. PYLORI QUIK CHEK test. The samples were prepared using a negative fecal matrix and spiked with H. pylori antigen (ATCC strain 43526). The panel consisted of 2 negative, 5 high negative (C5), 10 low positive (1-2x C95), and 15 positive specimens covering the range of the test (For fresh and preserved specimens this range was 50 ng/mL – 1200 ng/mL). Fresh samples were stored at refrigerated temperatures (between 2ºC and 8ºC) and room temperatures (between 20ºC and 25ºC) and were tested at 0, 24, 48,72 and 96 hours. Positive and negative controls were also tested at each timepoint. Fecal specimens added to Cary Blair and C&S media were transported as recommended in their respective package inserts; samples were stored at refrigerated temperatures (between 2ºC and 8ºC) and room temperatures (between 20ºC and 25ºC) and were tested at 24 hour intervals from 0 to 96 hours. 6
For fresh samples stored at refrigerated and room temperatures, the positive and negative samples gave the expected results 100% of the time. Storage in Cary Blair and C&S transport media did not affect the stability of the samples. Based on these results, the recommended storage time for fresh, Cary Blair, and C&S stored samples is up to 96 hours

83-Microbiology H. Intended Use: 1. Intended use(s): The TECHLAB H. PYLORI QUIK CHEK test is a rapid membrane enzyme immunoassay for the qualitative detection of Helicobacter pylori specific antigen in a single use cassette. It is intended for use with human fecal specimens to aid in the diagnosis of H. pylori infection and to demonstrate loss of H. pylori antigen following treatment. The test can be used with unpreserved fecal specimens and fecal specimens preserved in transport media from patients suspected of H. pylori infection. Testing of patients to demonstrate loss of H. pylori antigen following treatment should be performed no sooner than 4 weeks after completion of the treatment regimen. Test results should be taken into consideration by the physician in conjunction with the patient history and symptoms. 2. Indication(s) for use: Same as the Intended Use. 3. Special conditions for use statement(s): For prescription use only 4. Special instrument requirements: None I. Device Description: The H. PYLORI QUIK CHEK test utilizes antibodies specific for H. pylori antigen in human fecal samples. The Membrane Device contains a “Reaction Window” with two vertical lines of immobilized antibodies. The test line (“T”) contains antibodies specific for H. pylori antigen. The control line (“C”) contains antibodies to horseradish peroxidase (HRP). The “Conjugate” consists of antibodies to H. pylori antigen coupled to horseradish peroxidase. After incubation, the Reaction Window is examined visually for the appearance of vertical blue lines on the “C” and “T” sides of the Reaction Window. A blue line on the “T” side of the Reaction Window indicates a positive result. A positive “C” reaction, indicated by a vertical blue line on the “C” side of the Reaction Window, confirms that the sample and reagents were added correctly, the reagents were active at the time of performing the assay, and that the sample migrated properly through the Membrane Device. It also confirms the reactivity of the other reagents associated with the assay. 3

The samples were prepared using a negative fecal matrix and spiked with H. pylori antigen (ATCC strain 43526). The panel consisted of 2 negative, 5 high negative (C5), 10 low positive (1-2x C95), and 15 positive specimens covering the range of the test (For fresh and preserved specimens this range was 50 ng/mL – 1200 ng/mL). Fresh samples were stored at refrigerated temperatures (between 2ºC and 8ºC) and room temperatures (between 20ºC and 25ºC) and were tested at 0, 24, 48,72 and 96 hours. Positive and negative controls were also tested at each timepoint. Fecal specimens added to Cary Blair and C&S media were transported as recommended in their respective package inserts; samples were stored at refrigerated temperatures (between 2ºC and 8ºC) and room temperatures (between 20ºC and 25ºC) and were tested at 24 hour intervals from 0 to 96 hours. 6
For fresh samples stored at refrigerated and room temperatures, the positive and negative samples gave the expected results 100% of the time. Storage in Cary Blair and C&S transport media did not affect the stability of the samples. Based on these results, the recommended storage time for fresh, Cary Blair, and C&S stored samples is up to 96 hours

83-Microbiology H. Intended Use: 1. Intended use(s): The TECHLAB H. PYLORI QUIK CHEK test is a rapid membrane enzyme immunoassay for the qualitative detection of Helicobacter pylori specific antigen in a single use cassette. It is intended for use with human fecal specimens to aid in the diagnosis of H. pylori infection and to demonstrate loss of H. pylori antigen following treatment. The test can be used with unpreserved fecal specimens and fecal specimens preserved in transport media from patients suspected of H. pylori infection. Testing of patients to demonstrate loss of H. pylori antigen following treatment should be performed no sooner than 4 weeks after completion of the treatment regimen. Test results should be taken into consideration by the physician in conjunction with the patient history and symptoms. 2. Indication(s) for use: Same as the Intended Use. 3. Special conditions for use statement(s): For prescription use only 4. Special instrument requirements: None I. Device Description: The H. PYLORI QUIK CHEK test utilizes antibodies specific for H. pylori antigen in human fecal samples. The Membrane Device contains a “Reaction Window” with two vertical lines of immobilized antibodies. The test line (“T”) contains antibodies specific for H. pylori antigen. The control line (“C”) contains antibodies to horseradish peroxidase (HRP). The “Conjugate” consists of antibodies to H. pylori antigen coupled to horseradish peroxidase. After incubation, the Reaction Window is examined visually for the appearance of vertical blue lines on the “C” and “T” sides of the Reaction Window. A blue line on the “T” side of the Reaction Window indicates a positive result.

When the extracted specimen (~33mg/mL) is introduced to the sample well of the testing cassette, the specimen is absorbed into the device by capillary action, mixes with the hemoglobin specific mouse monoclonal antibody-dye conjugate, and flows across the pre-coated membrane. The bound complexes (antibody-dye conjugates/hHb) are then captured by antibodies immobilized 4
in the test region (T) of the device. When the hemoglobin antigen levels in specimens are at or above the target cut-off, the immobilized antibody-dye conjugate/antigen complex produces a colored test band and indicates a positive result. When the hemoglobin antigen levels in specimens are below the target cut-off, there is no visible colored band in the test region (T) of the device, indicating a negative result. To serve as a procedural control, a colored line will appear at the control region (C), if the test has been performed properly. M. Performance Characteristics: 1. Analytical performance: a. Precision/Reproducibility: Repeatability was evaluated using a single test kit lot and one operator; whereas reproducibility was conducted across three point-of-care (POC) sites in the U.S. using three test kit lots (one lot per site), three operators per site, performing one run per day for five non-consecutive days. For repeatability and reproducibility, Hb-free fecal samples were collected and spiked with hemoglobin to achieve the following seven fecal hemoglobin concentrations: 0 μg Hb/g stool, 1.2 μg Hb/g stool, 1.35 μg Hb/g stool, 1.5 μg Hb/g stool, 1.8 μg Hb/g stool, 2.25 μg Hb/g stool, and 60 μg Hb/g stool, that are equivalent to 0 ng/mL, 40 ng/mL, 45 ng/mL, 50 ng/mL, 60 ng/mL, 75 ng/mL and 2000 ng/mL, respectively. Twenty-one replicates were performed for each sample and concentration level. Repeatability and reproducibility results at all test sites passed acceptance criteria. Table 1.

b. Linearity/assay reportable range: Prozone (Hook Effect) Susceptibility of the Wondfo One Step Fecal Occult Blood (FOB) Test to prozone effects was evaluated using three test kit lots and three operators. Hemoglobin-free stool specimens were collected and spiked with human blood of known hemoglobin concentrations to obtain the following concentrations: 60000 μg Hb/g stool, 6000 μg Hb/g stool, 600 μg Hb/g stool, 60 μg Hb/g stool, 30 μg Hb/g stool, 15 μg Hb/g stool and 7.5 μg Hb/g stool. These concentrations are equivalent to the following hemoglobin concentrations when diluted with extraction buffer: 2 mg/mL, 200 μg/mL, 20 μg/mL, 2 μg/mL, 1 μg /mL, 500 ng/mL and 250 ng/mL respectively. Five aliquots of each sample mixed with extraction buffer in the specimen collection tubes were prepared and tested in a randomized order. It was determined that the Wondfo One Step Fecal Occult Blood (FOB) Test is not susceptible to prozone/hook effect up to a hemoglobin concentration of 200 μg/mL. c.

Some positive results may be seen earlier. Do not read results after 30 minutes. Read test results between 5-10 minutes. Test results read earlier than 5 minutes and later than 10 minutes are not valid. Storage 4–30°C 2–30°C K. Standard/Guidance Document Referenced (if applicable): Not applicable L. Test Principle: Wondfo One Step Fecal Occult Blood Test is a qualitative test designed for the immunochemical detection of human hemoglobin (hHb) in stool specimens. When the extracted specimen (~33mg/mL) is introduced to the sample well of the testing cassette, the specimen is absorbed into the device by capillary action, mixes with the hemoglobin specific mouse monoclonal antibody-dye conjugate, and flows across the pre-coated membrane. The bound complexes (antibody-dye conjugates/hHb) are then captured by antibodies immobilized 4
in the test region (T) of the device. When the hemoglobin antigen levels in specimens are at or above the target cut-off, the immobilized antibody-dye conjugate/antigen complex produces a colored test band and indicates a positive result. When the hemoglobin antigen levels in specimens are below the target cut-off, there is no visible colored band in the test region (T) of the device, indicating a negative result. To serve as a procedural control, a colored line will appear at the control region (C), if the test has been performed properly. M. Performance Characteristics: 1. Analytical performance: a. Precision/Reproducibility: Repeatability was evaluated using a single test kit lot and one operator; whereas reproducibility was conducted across three point-of-care (POC) sites in the U.S. using three test kit lots (one lot per site), three operators per site, performing one run per day for five non-consecutive days. For repeatability and reproducibility, Hb-free fecal samples were collected and spiked with hemoglobin to achieve the following seven fecal hemoglobin concentrations: 0 μg Hb/g stool, 1.2 μg Hb/g stool, 1.35 μg Hb/g stool, 1.5 μg Hb/g stool, 1.8 μg Hb/g stool, 2.25 μg Hb/g stool, and 60 μg Hb/g stool, that are equivalent to 0 ng/mL, 40 ng/mL, 45 ng/mL, 50 ng/mL, 60 ng/mL, 75 ng/mL and 2000 ng/mL, respectively. Twenty-one replicates were performed for each sample and concentration level. Repeatability and reproducibility results at all test sites passed acceptance criteria. Table 1.

Test results read earlier than 5 minutes and later than 10 minutes are not valid. Storage 4–30°C 2–30°C K. Standard/Guidance Document Referenced (if applicable): Not applicable L. Test Principle: Wondfo One Step Fecal Occult Blood Test is a qualitative test designed for the immunochemical detection of human hemoglobin (hHb) in stool specimens. When the extracted specimen (~33mg/mL) is introduced to the sample well of the testing cassette, the specimen is absorbed into the device by capillary action, mixes with the hemoglobin specific mouse monoclonal antibody-dye conjugate, and flows across the pre-coated membrane. The bound complexes (antibody-dye conjugates/hHb) are then captured by antibodies immobilized 4
in the test region (T) of the device. When the hemoglobin antigen levels in specimens are at or above the target cut-off, the immobilized antibody-dye conjugate/antigen complex produces a colored test band and indicates a positive result. When the hemoglobin antigen levels in specimens are below the target cut-off, there is no visible colored band in the test region (T) of the device, indicating a negative result. To serve as a procedural control, a colored line will appear at the control region (C), if the test has been performed properly. M. Performance Characteristics: 1. Analytical performance: a. Precision/Reproducibility: Repeatability was evaluated using a single test kit lot and one operator; whereas reproducibility was conducted across three point-of-care (POC) sites in the U.S. using three test kit lots (one lot per site), three operators per site, performing one run per day for five non-consecutive days. For repeatability and reproducibility, Hb-free fecal samples were collected and spiked with hemoglobin to achieve the following seven fecal hemoglobin concentrations: 0 μg Hb/g stool, 1.2 μg Hb/g stool, 1.35 μg Hb/g stool, 1.5 μg Hb/g stool, 1.8 μg Hb/g stool, 2.25 μg Hb/g stool, and 60 μg Hb/g stool, that are equivalent to 0 ng/mL, 40 ng/mL, 45 ng/mL, 50 ng/mL, 60 ng/mL, 75 ng/mL and 2000 ng/mL, respectively. Twenty-one replicates were performed for each sample and concentration level. Repeatability and reproducibility results at all test sites passed acceptance criteria. Table 1.

b. Linearity/assay reportable range: Prozone (Hook Effect) Susceptibility of the Wondfo One Step Fecal Occult Blood (FOB) Test to prozone effects was evaluated using three test kit lots and three operators. Hemoglobin-free stool specimens were collected and spiked with human blood of known hemoglobin concentrations to obtain the following concentrations: 60000 μg Hb/g stool, 6000 μg Hb/g stool, 600 μg Hb/g stool, 60 μg Hb/g stool, 30 μg Hb/g stool, 15 μg Hb/g stool and 7.5 μg Hb/g stool. These concentrations are equivalent to the following hemoglobin concentrations when diluted with extraction buffer: 2 mg/mL, 200 μg/mL, 20 μg/mL, 2 μg/mL, 1 μg /mL, 500 ng/mL and 250 ng/mL respectively. Five aliquots of each sample mixed with extraction buffer in the specimen collection tubes were prepared and tested in a randomized order. It was determined that the Wondfo One Step Fecal Occult Blood (FOB) Test is not susceptible to prozone/hook effect up to a hemoglobin concentration of 200 μg/mL. c.

b. Linearity/assay reportable range: Prozone (Hook Effect) Susceptibility of the Wondfo One Step Fecal Occult Blood (FOB) Test to prozone effects was evaluated using three test kit lots and three operators. Hemoglobin-free stool specimens were collected and spiked with human blood of known hemoglobin concentrations to obtain the following concentrations: 60000 μg Hb/g stool, 6000 μg Hb/g stool, 600 μg Hb/g stool, 60 μg Hb/g stool, 30 μg Hb/g stool, 15 μg Hb/g stool and 7.5 μg Hb/g stool. These concentrations are equivalent to the following hemoglobin concentrations when diluted with extraction buffer: 2 mg/mL, 200 μg/mL, 20 μg/mL, 2 μg/mL, 1 μg /mL, 500 ng/mL and 250 ng/mL respectively. Five aliquots of each sample mixed with extraction buffer in the specimen collection tubes were prepared and tested in a randomized order. It was determined that the Wondfo One Step Fecal Occult Blood (FOB) Test is not susceptible to prozone/hook effect up to a hemoglobin concentration of 200 μg/mL. c.

Other Supportive Instrument Performance Characteristics Data Not Covered In The “Performance Characteristics” Section above: 1. Test Kit Reaction Time: 14 The Wondfo One Step Fecal Occult Blood (FOB) Test reaction time was demonstrated by using seven stool concentrations at eight different time points. Reaction time test samples were prepared by spiking Hb-free stool specimen with known levels of human Hb solution to obtain fecal samples with seven different Hb concentrations: 0 μg Hb/g stool, 1.2 μg Hb/g stool, 1.35 μg Hb/g stool, 1.5 μg Hb/g stool, 1.8 μg Hb/g stool, 2.25 μg Hb/g stool, and 60 μg Hb/g stool, that are equivalent to 0, 40, 45, 50, 60, 75 and 2000 ng/mL, respectively. Twenty one replicates of each sample were collected with Wondfo One Step Fecal Occult Blood (FOB) Test sample collection tubes. All specimens were tested with one test kit lot in a randomized and blinded manner by one operator. The test results were read and recorded at 3, 5, 8, 10, 20, 30, 40 and 60 minutes. Positivity rate of 0 ng/mL was 0%, positivity rate of 40 ng/mL was 4.8%, positivity rate of 45 ng/mL was 47.6%, and the positivity rate of 50 ng/mL was 100% at 10 minutes of reaction. The appropriate reaction time of Wondfo One Step Fecal Occult Blood (FOB) Test was demonstrated as 10 minutes. 2. Operator Intensity Reading: The operator intensity reading test was performed by utilizing test samples prepared by spiking Hb-free stool specimen with known levels of human Hb solution to obtain fecal samples with seven different Hb concentrations: 0 μg Hb/g stool, 1.2 μg Hb/g stool, 1.35 μg Hb/g stool, 1.5 μg Hb/g stool, 1.8 μg Hb/g stool, 2.25 μg Hb/g stool, and 60 μg Hb/g stool, that are equivalent to 0, 40 , 45, 50, 60, 75 and 2000 ng/mL, respectively. Twenty-five replicates were prepared for each concentration. All specimens were tested with one test kit lot in a randomized and blinded manner by five different readers at one intended use site. The study participants recorded the results and graded the intensity of the test line from 10 levels: (B (no test line), C9 (faint test line), C8, C7, C6, C5, C4, C3, C2 and C1 (deepest test line). The intensity of the test line increased in correlation with the Hb concentration of stool test samples. There was no statistical significance in the analyses of the test samples performed by the operators for the intensity reading test study. 3. Specimen Collection Verification: Verification that the applicator device for the Wondfo One Step Fecal Occult Blood (FOB) Test consistently delivers the specified amount of stool required for optimal test performance was performed by five lay users using five positive and five negative clinical samples per lay user. The study was performed at one intended use site. Five positive and 5 negative clinical samples results were confirmed using the predicate device and the proposed device. A professional operator used an electronic balance and weighed the sampling stick first so that this weight could be offset. The lay users then inserted the sampling stick into test stool sample at six different sites to collect samples and placed the sampling stick back in to the sample collection tube (without buffer). After, the professional operator used the electronic balance to weigh the sample stick with stool sample. The lay users next used three sample collection tubes (with buffer) to collect the sample again and used three test cassettes of Wondfo One Step Fecal Occult Blood (FOB) Test to test the result according to the test procedure directions of the package insert. The average value for sample volume collected was 0.0517g and the standard deviation was 0.0027, 15
which demonstrated the consistency of the sampling. The total positive and negative results obtained by the lay users are consistent with the expected results for the test samples. The lay users collected adequate consistent amounts of stool samples when following the package insert directions to perform the Wondfo One Step Fecal Occult Blood (FOB) Test. Q.

Standard/Guidance Document Referenced (if applicable): CLSI M100 28th Edition, Performance Standards for Antimicrobial Susceptibility Testing L. Test Principle: The HardyDisk AST Disk is based on the agar diffusion (Kirby-Bauer) methodology. It utilizes dried filter paper disks impregnated with a known concentration of an antimicrobial agent that are placed onto the test medium surface. Mueller Hinton agar is recommended for agar diffusion testing of non-fastidious organisms and Mueller Hinton with 5% Sheep Blood 5
is recommended for Streptococcus spp. Three to five similar colonies are transferred to 4-5 mL of a suitable broth medium. The broth is incubated at 35°C for 2-6 hours to develop a turbidity that exceeds or is equivalent to a 0.5 McFarland standard. Alternatively, a direct broth or saline suspension of colonies may be prepared from an overnight culture. The final inoculum density should be equivalent to a 0.5 McFarland turbidity standard. The inoculum density may also be standardized photometrically. Within 15 minutes of inoculum preparation, the Mueller Hinton agar plate is streaked with an inoculated swab to obtain an even inoculation of organism. Disks are aseptically placed onto the agar surface with a disk dispenser and the disks are pressed down with a sterile needle or forceps to make contact with the agar surface. Agar plates are incubated in an ambient air incubator at 35±2°C for 16 - 18 hours. Fastidious organisms are tested using appropriate media incubated in an atmosphere enriched with 5% CO2, as recommended in the CLSI M02 approved standard document. After incubation the agar medium is examined for a zone of inhibition around the disks. The zones of inhibition are measured to the nearest millimeter and compared to recognized zone size ranges for the antimicrobial agent being tested. M. Performance Characteristics (if/when applicable): Descriptive characteristics were sufficient for the HardyDisk Plazomicin 30µg (PLZ30) disk based on extensive data from several microbiology disk studies evaluated by CDER which were used to generate the breakpoints and quality control (QC) expected ranges used for this subject device. The disk data used to support this submission included data from testing organisms within the spectrum of activity of plazomicin. Data was obtained from reproducibility, quality control and disk to MIC correlation studies and was generated in accordance with the CDER Clinical/Antimicrobial guidance, Microbiology Data for Systemic Antibacterial Drugs- Development, Analysis, and Presentation to ensure precise, accurate, and reproducible results. For this review, the interpretative criteria are applied broadly to include the Enterobacteriaceae family. The list of bacterial species has been expanded and is not limited only to the indicated species. The following statements are added as footnotes to the plazomicin interpretative criteria table for Enterobacteriaceae in the HardyDisk AST package insert: The statement below is added to the package insert and is consistent with the FDA STIC website: o The safety and efficacy of plazomicin in treating clinical infections due to organisms other than Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, and Enterobacter cloacae may not have been established in adequate and well-
controlled clinical trials. The clinical significance of susceptibility information in such instances is unknown. 6

Standard/Guidance Document Referenced (if applicable): CLSI M100 28th Edition, Performance Standards for Antimicrobial Susceptibility Testing L. Test Principle: The HardyDisk AST Disk is based on the agar diffusion (Kirby-Bauer) methodology. It utilizes dried filter paper disks impregnated with a known concentration of an antimicrobial agent that are placed onto the test medium surface. Mueller Hinton agar is recommended for agar diffusion testing of non-fastidious organisms and Mueller Hinton with 5% Sheep Blood 5
is recommended for Streptococcus spp. Three to five similar colonies are transferred to 4-5 mL of a suitable broth medium. The broth is incubated at 35°C for 2-6 hours to develop a turbidity that exceeds or is equivalent to a 0.5 McFarland standard. Alternatively, a direct broth or saline suspension of colonies may be prepared from an overnight culture. The final inoculum density should be equivalent to a 0.5 McFarland turbidity standard. The inoculum density may also be standardized photometrically. Within 15 minutes of inoculum preparation, the Mueller Hinton agar plate is streaked with an inoculated swab to obtain an even inoculation of organism. Disks are aseptically placed onto the agar surface with a disk dispenser and the disks are pressed down with a sterile needle or forceps to make contact with the agar surface. Agar plates are incubated in an ambient air incubator at 35±2°C for 16 - 18 hours. Fastidious organisms are tested using appropriate media incubated in an atmosphere enriched with 5% CO2, as recommended in the CLSI M02 approved standard document. After incubation the agar medium is examined for a zone of inhibition around the disks. The zones of inhibition are measured to the nearest millimeter and compared to recognized zone size ranges for the antimicrobial agent being tested. M. Performance Characteristics (if/when applicable): Descriptive characteristics were sufficient for the HardyDisk Plazomicin 30µg (PLZ30) disk based on extensive data from several microbiology disk studies evaluated by CDER which were used to generate the breakpoints and quality control (QC) expected ranges used for this subject device. The disk data used to support this submission included data from testing organisms within the spectrum of activity of plazomicin. Data was obtained from reproducibility, quality control and disk to MIC correlation studies and was generated in accordance with the CDER Clinical/Antimicrobial guidance, Microbiology Data for Systemic Antibacterial Drugs- Development, Analysis, and Presentation to ensure precise, accurate, and reproducible results. For this review, the interpretative criteria are applied broadly to include the Enterobacteriaceae family. The list of bacterial species has been expanded and is not limited only to the indicated species. The following statements are added as footnotes to the plazomicin interpretative criteria table for Enterobacteriaceae in the HardyDisk AST package insert: The statement below is added to the package insert and is consistent with the FDA STIC website: o The safety and efficacy of plazomicin in treating clinical infections due to organisms other than Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, and Enterobacter cloacae may not have been established in adequate and well-

Standard/Guidance Document Referenced (if applicable): CLSI M100 28th Edition, Performance Standards for Antimicrobial Susceptibility Testing L. Test Principle: The HardyDisk AST Disk is based on the agar diffusion (Kirby-Bauer) methodology. It utilizes dried filter paper disks impregnated with a known concentration of an antimicrobial agent that are placed onto the test medium surface. Mueller Hinton agar is recommended for agar diffusion testing of non-fastidious organisms and Mueller Hinton with 5% Sheep Blood 5
is recommended for Streptococcus spp. Three to five similar colonies are transferred to 4-5 mL of a suitable broth medium. The broth is incubated at 35°C for 2-6 hours to develop a turbidity that exceeds or is equivalent to a 0.5 McFarland standard. Alternatively, a direct broth or saline suspension of colonies may be prepared from an overnight culture. The final inoculum density should be equivalent to a 0.5 McFarland turbidity standard. The inoculum density may also be standardized photometrically. Within 15 minutes of inoculum preparation, the Mueller Hinton agar plate is streaked with an inoculated swab to obtain an even inoculation of organism. Disks are aseptically placed onto the agar surface with a disk dispenser and the disks are pressed down with a sterile needle or forceps to make contact with the agar surface. Agar plates are incubated in an ambient air incubator at 35±2°C for 16 - 18 hours. Fastidious organisms are tested using appropriate media incubated in an atmosphere enriched with 5% CO2, as recommended in the CLSI M02 approved standard document. After incubation the agar medium is examined for a zone of inhibition around the disks. The zones of inhibition are measured to the nearest millimeter and compared to recognized zone size ranges for the antimicrobial agent being tested. M. Performance Characteristics (if/when applicable): Descriptive characteristics were sufficient for the HardyDisk Plazomicin 30µg (PLZ30) disk based on extensive data from several microbiology disk studies evaluated by CDER which were used to generate the breakpoints and quality control (QC) expected ranges used for this subject device. The disk data used to support this submission included data from testing organisms within the spectrum of activity of plazomicin. Data was obtained from reproducibility, quality control and disk to MIC correlation studies and was generated in accordance with the CDER Clinical/Antimicrobial guidance, Microbiology Data for Systemic Antibacterial Drugs- Development, Analysis, and Presentation to ensure precise, accurate, and reproducible results. For this review, the interpretative criteria are applied broadly to include the Enterobacteriaceae family. The list of bacterial species has been expanded and is not limited only to the indicated species. The following statements are added as footnotes to the plazomicin interpretative criteria table for Enterobacteriaceae in the HardyDisk AST package insert: The statement below is added to the package insert and is consistent with the FDA STIC website: o The safety and efficacy of plazomicin in treating clinical infections due to organisms other than Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, and Enterobacter cloacae may not have been established in adequate and well-

Standard/Guidance Document Referenced (if applicable): CLSI M100 28th Edition, Performance Standards for Antimicrobial Susceptibility Testing L. Test Principle: The HardyDisk AST Disk is based on the agar diffusion (Kirby-Bauer) methodology. It utilizes dried filter paper disks impregnated with a known concentration of an antimicrobial agent that are placed onto the test medium surface. Mueller Hinton agar is recommended for agar diffusion testing of non-fastidious organisms and Mueller Hinton with 5% Sheep Blood 5
is recommended for Streptococcus spp. Three to five similar colonies are transferred to 4-5 mL of a suitable broth medium. The broth is incubated at 35°C for 2-6 hours to develop a turbidity that exceeds or is equivalent to a 0.5 McFarland standard. Alternatively, a direct broth or saline suspension of colonies may be prepared from an overnight culture. The final inoculum density should be equivalent to a 0.5 McFarland turbidity standard. The inoculum density may also be standardized photometrically. Within 15 minutes of inoculum preparation, the Mueller Hinton agar plate is streaked with an inoculated swab to obtain an even inoculation of organism. Disks are aseptically placed onto the agar surface with a disk dispenser and the disks are pressed down with a sterile needle or forceps to make contact with the agar surface. Agar plates are incubated in an ambient air incubator at 35±2°C for 16 - 18 hours. Fastidious organisms are tested using appropriate media incubated in an atmosphere enriched with 5% CO2, as recommended in the CLSI M02 approved standard document. After incubation the agar medium is examined for a zone of inhibition around the disks. The zones of inhibition are measured to the nearest millimeter and compared to recognized zone size ranges for the antimicrobial agent being tested. M. Performance Characteristics (if/when applicable): Descriptive characteristics were sufficient for the HardyDisk Plazomicin 30µg (PLZ30) disk based on extensive data from several microbiology disk studies evaluated by CDER which were used to generate the breakpoints and quality control (QC) expected ranges used for this subject device. The disk data used to support this submission included data from testing organisms within the spectrum of activity of plazomicin. Data was obtained from reproducibility, quality control and disk to MIC correlation studies and was generated in accordance with the CDER Clinical/Antimicrobial guidance, Microbiology Data for Systemic Antibacterial Drugs- Development, Analysis, and Presentation to ensure precise, accurate, and reproducible results. For this review, the interpretative criteria are applied broadly to include the Enterobacteriaceae family. The list of bacterial species has been expanded and is not limited only to the indicated species. The following statements are added as footnotes to the plazomicin interpretative criteria table for Enterobacteriaceae in the HardyDisk AST package insert: The statement below is added to the package insert and is consistent with the FDA STIC website: o The safety and efficacy of plazomicin in treating clinical infections due to organisms other than Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, and Enterobacter cloacae may not have been established in adequate and well-

analytical collection error and specifically in patients with decreased peripheral blood flow, as it may not reflect the true physiological state. Examples include, but are not limited to, severe hypotension, shock, hyperosmolar-hyperglycemia (with or without ketosis) and severe dehydration. The system has not been evaluated for use with neonate venous blood. Temperature and humidity extremes - Test results may be inaccurate when test strips are stored outside of the storage and handling conditions. Altitudes above 15,000 feet (4500 meters) above sea level have not been evaluated. Specimens - Only fresh whole blood or whole blood collected in lithium heparin collection devices should be used for arterial and venous specimens. Fluoride, EDTA, Sodium, and Ammonium blood collection devices should not be used. Use only whole blood. Do not use serum or plasma.

Standard/Guidance Document Referenced (if applicable): Class II Special Controls Guideline Document: Toxin Gene Amplification Assays for the Detection of Clostridium difficile, August 27, 2015. L. Test Principle: A small amount of specimen is transferred to a Lysis Tube using a swab. The Lysis Tube is then subjected to heat‐treatment at 95 °C for five minutes. The heat‐treated sample is added to a Dilution Tube, and then transferred to a Reaction Tube. The Reaction Tube contains lyophilized HDA reagents, dNTPs, primers and probes. Once rehydrated with the diluted sample, the Reaction Tube is placed in Solana for amplification and detection of target sequence. In Solana, the target sequence is amplified by specific primers and detected by a specific fluorescence probe included in the Reaction Tube. A competitive process control (PRC) is included in the Lysis Tube to monitor sample processing, inhibitory substances in clinical samples, reagent failure or device failure. The PRC is amplified by the target‐specific primers and detected by a PRC specific fluorescence probe. The target and PRC probes are labeled with a quencher on one end and a fluorophore on the other end. Upon annealing to target or PRC amplicons, the fluorescence signal increases due to physical separation of fluorophore from quencher. Solana measures and interprets the fluorescent signal, using on‐board method‐specific algorithms. Solana then report the test results to the user on its display screen, and it can print out the results via a printer. 5
M. Performance Characteristics (if/when applicable): 1. Analytical performance: a. Precision/Reproducibility: To evaluate the reproducibility of the Solana C. difficile Assay, a blinded and randomized study panel was tested at one internal site and two external clinical sites. The panel was contrived in negative stool matrix and consisted of negative samples and positive samples spiked with toxigenic C. difficile at the following three organism concentration levels: moderate positive (3.4 x 103 CFU/mL), low positive (1.7 x 103 CFU/mL), and high negative (4.8 x 102 CFU/mL). Each site tested the panel and external positive and negative controls in triplicate for five non-consecutive days. Testing was conducted by two operators at each site with two runs per day. The Solana C. difficile Assay produced the expected results in 98.9% (89/90) of the low positive samples, 100% (90/90) of the moderate positive samples, and 100% (90/90) of the negative samples. The assay produced positive results in 47.8% (43/90) of the high negative samples which was within the expected range of 20 to 80% positive results. The results did not vary between sites, days, or runs. The external positive and negative controls produced the expected results for all replicates and no invalid control results were observed during the study. The reproducibility study results were acceptable. The results are summarized in Table 1. Table 1.

Standard/Guidance Document Referenced (if applicable): Class II Special Controls Guideline Document: Toxin Gene Amplification Assays for the Detection of Clostridium difficile, August 27, 2015. L. Test Principle: A small amount of specimen is transferred to a Lysis Tube using a swab. The Lysis Tube is then subjected to heat‐treatment at 95 °C for five minutes. The heat‐treated sample is added to a Dilution Tube, and then transferred to a Reaction Tube. The Reaction Tube contains lyophilized HDA reagents, dNTPs, primers and probes. Once rehydrated with the diluted sample, the Reaction Tube is placed in Solana for amplification and detection of target sequence. In Solana, the target sequence is amplified by specific primers and detected by a specific fluorescence probe included in the Reaction Tube. A competitive process control (PRC) is included in the Lysis Tube to monitor sample processing, inhibitory substances in clinical samples, reagent failure or device failure. The PRC is amplified by the target‐specific primers and detected by a PRC specific fluorescence probe. The target and PRC probes are labeled with a quencher on one end and a fluorophore on the other end. Upon annealing to target or PRC amplicons, the fluorescence signal increases due to physical separation of fluorophore from quencher. Solana measures and interprets the fluorescent signal, using on‐board method‐specific algorithms. Solana then report the test results to the user on its display screen, and it can print out the results via a printer. 5
M. Performance Characteristics (if/when applicable): 1. Analytical performance: a. Precision/Reproducibility: To evaluate the reproducibility of the Solana C. difficile Assay, a blinded and randomized study panel was tested at one internal site and two external clinical sites. The panel was contrived in negative stool matrix and consisted of negative samples and positive samples spiked with toxigenic C. difficile at the following three organism concentration levels: moderate positive (3.4 x 103 CFU/mL), low positive (1.7 x 103 CFU/mL), and high negative (4.8 x 102 CFU/mL). Each site tested the panel and external positive and negative controls in triplicate for five non-consecutive days. Testing was conducted by two operators at each site with two runs per day. The Solana C. difficile Assay produced the expected results in 98.9% (89/90) of the low positive samples, 100% (90/90) of the moderate positive samples, and 100% (90/90) of the negative samples. The assay produced positive results in 47.8% (43/90) of the high negative samples which was within the expected range of 20 to 80% positive results. The results did not vary between sites, days, or runs. The external positive and negative controls produced the expected results for all replicates and no invalid control results were observed during the study. The reproducibility study results were acceptable. The results are summarized in Table 1. Table 1.

Standard/Guidance Document Referenced (if applicable): Class II Special Controls Guideline Document: Toxin Gene Amplification Assays for the Detection of Clostridium difficile, August 27, 2015. L. Test Principle: A small amount of specimen is transferred to a Lysis Tube using a swab. The Lysis Tube is then subjected to heat‐treatment at 95 °C for five minutes. The heat‐treated sample is added to a Dilution Tube, and then transferred to a Reaction Tube. The Reaction Tube contains lyophilized HDA reagents, dNTPs, primers and probes. Once rehydrated with the diluted sample, the Reaction Tube is placed in Solana for amplification and detection of target sequence. In Solana, the target sequence is amplified by specific primers and detected by a specific fluorescence probe included in the Reaction Tube. A competitive process control (PRC) is included in the Lysis Tube to monitor sample processing, inhibitory substances in clinical samples, reagent failure or device failure. The PRC is amplified by the target‐specific primers and detected by a PRC specific fluorescence probe. The target and PRC probes are labeled with a quencher on one end and a fluorophore on the other end. Upon annealing to target or PRC amplicons, the fluorescence signal increases due to physical separation of fluorophore from quencher. Solana measures and interprets the fluorescent signal, using on‐board method‐specific algorithms. Solana then report the test results to the user on its display screen, and it can print out the results via a printer. 5
M. Performance Characteristics (if/when applicable): 1. Analytical performance: a. Precision/Reproducibility: To evaluate the reproducibility of the Solana C. difficile Assay, a blinded and randomized study panel was tested at one internal site and two external clinical sites. The panel was contrived in negative stool matrix and consisted of negative samples and positive samples spiked with toxigenic C. difficile at the following three organism concentration levels: moderate positive (3.4 x 103 CFU/mL), low positive (1.7 x 103 CFU/mL), and high negative (4.8 x 102 CFU/mL). Each site tested the panel and external positive and negative controls in triplicate for five non-consecutive days. Testing was conducted by two operators at each site with two runs per day. The Solana C. difficile Assay produced the expected results in 98.9% (89/90) of the low positive samples, 100% (90/90) of the moderate positive samples, and 100% (90/90) of the negative samples. The assay produced positive results in 47.8% (43/90) of the high negative samples which was within the expected range of 20 to 80% positive results. The results did not vary between sites, days, or runs. The external positive and negative controls produced the expected results for all replicates and no invalid control results were observed during the study. The reproducibility study results were acceptable. The results are summarized in Table 1. Table 1.
